For sure, it’s almost certainly a “growth hacking” attempt (they’re hoping the ppl they email signup to otter.ai), but a pretty terrible one. Every other similar growth hacking attempt I’ve seen will explicitly ask for consent before sending anything to non-users of the app.
Overall, sounds like a VERY unscrupulous company, that you shouldn’t trust with your personal data.
Even more terrible is using a recording service when you're in a meeting with me, not telling me, then complaining the real problem is the service told me
As understandable as the mistake is, I would be upset if I had arranged a private meeting with someone and they let a third party into the conversation (excluding force majeure such as sophisticated hacking, violence, etc).
Especially if it was some unaccountable third party recording agent! Who knows where that data is going?
